A source of air enters nozzle 174 through conduit 176. Appropriate venting device 178 is seen in line 176 to regulate the amount of air entering nozzle 174. While a spindle 170 "is described for supporting the lap of curled rope, it will be understood that other suitable lap carriers could be used to unwind the curled rope from the lap. For example, instead of rotating the roll 58, the curled rope may be delivered to the nozzle 174 "over end * ¹ from a stationary roll which is supported in a suitable manner.
